templates for different directory roles.

:'global.mk': This file contains global variables, for example the

definitions of the tools to use.

:'prg.mk': This file represents the target binary role of a directory.

It must be included by all makefiles that build programs.

within the 'src/' directory but only from the <libname>.mk files
